Is this trial a fit for you?

Likely a good fit

Ideal candidates are healthy adults currently enrolled or scheduled to enroll in a respiratory virus challenge study at the NIH.

Probably not a fit

Patients with conditions that may interfere with the ability to wear monitoring devices or provide informed consent may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study aims to utilize wearable and sensor devices, such as smartwatches and smartphones, to collect health data from participants enrolled in respiratory virus challenge studies. Participants will wear these devices continuously during their stay at the NIH Clinical Center and during follow-up visits to monitor various health metrics, including cough frequency, heart rate, and temperature. The goal is to identify digital biomarkers that correlate with respiratory virus infections and develop predictive models for influenza disease severity. By analyzing the data collected, researchers hope to uncover subtle health changes that may indicate infection.

Why it matters

Potential benefit: If successful, this study could lead to improved monitoring and early detection of respiratory virus infections, enhancing patient care.

How similar studies have gone: While the use of digital devices in monitoring health is gaining traction, this specific approach to correlate digital biomarkers with respiratory virus infections is relatively novel.
